The Blake Corrugated Board Envelope (PCE70) is designed for professionals and individuals who require high-strength, secure transit solutions for A3+ sized documents or bulky items. Its primary benefit is the combination of rigid, shock-absorbing corrugated cardboard and a tamper-evident rip strip, providing peace of mind during shipping. Please note that while the material is robust, it is not waterproof, so extra protection may be needed if shipping in adverse weather conditions.

Yes, at 490 x 330mm, these envelopes are larger than standard A3 paper, providing a comfortable fit with room to spare.
Yes, these envelopes are made from 100% recycled materials.
The integrated rip strip is tamper-evident; once the strip is removed, it cannot be resealed in its original state.
Ensure the surface area is free of dust or debris and hold firm pressure on the flap for at least 5-10 seconds.
Use the internal fold lines to expand the depth. If the contents are still too tight, consider a larger packaging alternative to avoid splitting the seams.
To ensure optimal performance, keep these envelopes in a cool, dry place to prevent moisture from weakening the cardboard or degrading the adhesive seal. When preparing a shipment, ensure the contents do not exceed the structural limits of the internal expansion lines to avoid tearing the sides. The peel and seal adhesive is pressure-sensitive; after folding the flap down, apply firm, even pressure across the entire adhesive line to ensure a complete bond. These envelopes are intended for standard courier and postal shipping and are compatible with all major logistics carriers.
